Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- ' all, every ' and γραφ- ' to write ', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...
This configuration is also called a pantograph, [2] [3] however, it is not to be confused with the parallelogram-copying linkage pantograph. The linkage can be a one-degree-of-freedom mechanism if two gears are attached to two links and are meshed together, forming a geared five-bar mechanism.
The parallel motion differed from Watt's linkage by having an additional pantograph linkage incorporated in the design. This did not affect the fundamental principle but it allowed the engine room to be smaller because the linkage was more compact. [2] The Newcomen engine's piston was propelled downward by the atmospheric pressure.
In a telecommunications network, a link is a communication channel that connects two or more devices for the purpose of data transmission.The link may be a dedicated physical link or a virtual circuit that uses one or more physical links or shares a physical link with other telecommunications links.
A pantograph is a mechanical connected linkage of a writing instrument, like a pen, such that the movement of one pen, in tracing an image, produces identical movements in a second pen. Pantograph may also refer to: Pantograph (lighting suspension), an overhead lighting system used in television and photography
Linkage mobility Locking pliers exemplify a four-bar, one degree of freedom mechanical linkage. The adjustable base pivot makes this a two degree-of-freedom five-bar linkage. It is common practice to design the linkage system so that the movement of all of the bodies are constrained to lie on parallel planes, to form what is known as a planar ...
The diamond-shaped, electric-rod pantograph of the Swiss cogwheel locomotive of the Schynige Platte railway in Schynige Platte, built in 1911 Cross-arm pantograph of a Toshiba EMU. A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or trolley buses [1] to collect power through contact with an ...
Example of a void pantograph pattern before (left) and after (right) the document has been photocopied. In security printing, void pantograph refers to a method of making copy-evident and tamper-resistant patterns in the background of a document. Normally these are invisible to the eye, but become obvious when the document is photocopied.
